SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 393,728, dated November 27, 1888.

Application filed July 28, 1888.

To aZZ whom it 11mg concern.-

Be it known that I, PLEASANT W. SUoos, a citizen of the United States, residing at Mobile, in the county of Mobile and State of Alabama, have invented new and useful Improvements in Sash-Holders, of which the following is a specification.

My invention relates to improvements in sash-holders; and it consists in certain novel features hereinafter described and claimed.

In the accompanying drawings, which fully illustrate my invention, Figure 1 is a front elevation of a window provided with my improved device, the holder on the lower sash being arranged to prevent raising of the same, and the holder on the upper sash being arranged to prevent lowering thereof. Fig. 2 is a detail view showing different positions of the base-plate to illustrate the manner of adjusting the lock to the width of the sash. Fig.

3 is a detail section, and Fig. 4 the lever detached. Referring to the drawings by letter, A B designate the upper and lower sashes,respectively, of a window constructed in the usual or any preferred manncr,and sliding between the usual beads, O, as shown. On the inner face of the bead I secure a suitable number of lugs or stops, D,which consist of suitable metallic blocks screwed or otherwise rigidly secured to the bead and providedin their upper and lower edges with the grooves E,as clearly shown.

The front faces of the sashes are provided near their lower ends with recesses F, in which the base-plates G are secured. The recesses and the base-plates are circular, as shown,and the baseplates are secured in the recesses by means of screws H,whieh are countersunk, so as not to interfere with the movement of the locking-pawl I. This locking-pawl is pivotally mounted on the base-plate by means of a pin or screw, J and it consists of a pivotal circular portion, K, provided with a trans verse openingfor the passage of the pivot-pin, and a weighted portion, L, to one side of the pivot-opening,and a blade or locking-arm, M, extending from the pivotal circular portion and springingfrom thccdge of the same near one end'of the weight L. This blade or looking- Scrial K032815308. (No model.)

arm is tapered longitudinally toward its free end and widened laterally, thereby forming a knife-edge, N, which is adapted to engage the grooves in the lugs or stops D in the opera tion of the device.

In practice the base-plates are secured in the recesses in the sashes and the pawls are pivotally mounted on the same, the weighted portion L, together with the weight of the blade, causing the said bladeto swing toward the bead into position to engage the stops, as shown, and thereby prevent vertical movement of the sash. The pawl can be readily adjusted to preventeithcr raising or lowering of the sash, as may be desired, and as will be readily understood on reference to the drawings. When the pawl is arranged to project upward,it-s edge engages the groove in the under side of the stop and prevents the raising of the sash. When the pawl projects downward, it engages the upper side of the stop and prevents lowering of the sash.

The holder does notinterfere with the properoperation of the sashes, as it projects from the sashes a distance slightly less than the thickness of the beads.

The pawl is pivoted upon the base-plate at a point to one side of the center of the same, so

that the device can be readily adjusted to properly engage the stops. Should the sash shrink or wear loose, thereby leaving the pawl too far from the bead, the securing-screws are removed, the base-plate turned in the recess in the sash to bring the pivot of the pawl nearer the bead, and then again secured, as will be readily understood on reference to Fig. 2, the old screw-holes being hid by the base plate.

My device is very cheap and simple, and its advantages are thought to be obvious.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, is-- As an improvement in sash-holders, the combination of the window-frame, the stopblocks secured thereto, having transverse grooves in their upper and lower edges, the sashes provided with circular recesses in their frontfaces, the circular base-plates secured in said recesses, and the pawls, each comprising a weighted portion pivoted on one of the baseown I have hereto affixed my signature in pres plates at one side of the center of the said ence of two witnesses. base-plate, and a blade extending from said weighted portion and having its end engaging 5 the groove in one of the edges of one of the t \Vitnesses:

stop-blocks, as specified. G. M. WoRTHINGToN, In testimony that I claim the foregoing as m y .T. M. HENDERSON.
